Abstract: 1,008,774. Ratchet clutches. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Aug. 31, 1962 [Oct. 13, 1961], No. 36793/61. Heading F2C. [Also in Division B7] A clutch has two spools 22a, 22b carried on oppositely-handed, threaded portions 30a, 30b of a spindle 30 mounted in bearings 31, 32 and carrying a spool 34. A collar 33 prevents separation of the spools 22a, 22b. When the spools 22a, 22b rotate in opposite directions they move together up or down spindle 30; but on rotation in the same sense they tend to abut or separate and so become locked together to prevent their rotation on the spindle which with the spool 34 is therefore rotated.

HESSER MASCHINENFABRIK AKT.-GES., F., 99, Olgastrasse, Stuttgart, Canstatt, and G A N G L E R , P., 53, Panoramastrasse, Esslingen-on-Neckar, both in Germany. Dec. 31, 1932, No. 37063. [Class 143.] A machine for filling and closing cartons is provided with a weighing-device and associated means for preventing the proper closing of insufficiently filled cartons, so that they are recognizable on leaving the machine. The machine is diagrammatically shown in plan in Fig. 1 in which I represents a rotary filling apparatus operating in timed relationship with a closing apparatus II. The package is introduced at e into a pocket in the rotary system I, and filled and shaken at stations f, g, h. At a, the carton arrives over the arm 3 of a weighing device, and, if the weight is correct, prevents the lever 2 from rocking. If the weight is incorrect, the lever 2 rocks and closes a circuit to energize a magnet 23 arranged at station a<1>. An armature 22, Fig. 2, on a lever 16 is raised and allows a bolt 14 to move outwards under the influence of a spring 18. A bolt is provided to correspond with and to rotate with each pocket of the closing device. As the station a<1> is the same number of stages from the transfer station c, c<1> as is the station a, the defective packet is introduced, from station c into the pocket c<1> corresponding to the sleeve 13 in which the bolt 14 has been displaced. The packet now moves towards station f<1>, at which gum is to be applied to the flaps. If, however, the bolt 14 has been projected, it depresses a lever 25 at station f<1>, having a tail 29 which moves a locking lever 31 to the right, Fig. 2. A hook 31<1> on the lever prevents the gumming mechanism from operating, and the later flap. closing operations are ineffective. The defective package is therefore recognizable;and may be taken away for hand-closing and filling.

Title: Improvements in or relating to modulation systems for modulating generators of high frequency electrical oscillations
IPC: H03C7/02
Filed: 1938-12-22
Abstract: 522,976. Modulating systems. PAWSEY, J. L., and WHITE, E. L. C. Dec. 22, 1938, No. 37240. [Class 40 (v)] An ultra high frequency generator is connected to the branch point of two paths in which modulation is effected in such a manner that the impedance presented to the generator is substantially unaffected by the degree of modulation. One of the paths is terminated in the load and the other in a terminating impedance. The Figure shows an arrangement in which a co-axial line 10 connects a generator to the branch point 11 of a pair of lines 12, 13, both of the same characteristic impedance as the line 10. Modulation is effected at points 14, 15 each a quarter wavelength, or an odd multiple thereof, from the branch point 11 by variable impedance devices so controlled by the modulating signal that the product of their impedances is equal to the square of the characteristic impedance of the line. In this way when the lines are connected at their remote ends to impedances equal to the characteristic impedance of the line the high frequency oscillations fed into the system appear modulated by the signal at either of the remote ends of the lines. The Figure shows triode modulators 16, 20 and the necessity for applying correctly related control potentials to the grids so that the correct product of the impedances is produced is avoided by connecting the valve 16 through a quarter wave line 24 so that if the same potentials are applied to the grids of the valves 16, 20 the required conditions are satisfied if the characteristic impedance of the line 24 is the same as that of the other lines.

Filed: 1968-08-06
Abstract: 1,271,647. Rear-view mirrors. Y. J. TALBOT. 28 July, 1969 [6 Aug., 1968], No. 37363/68. Heading B7J. An external driving mirror for motor vehicles comprises a mounting 4 connecting one end of an arm 1 to the vehicle front door, the other end of the arm adjustably carrying a mirror unit 7, the arrangement being such that when the mirror unit receives an impact it tends to be deflected to lie substantially parallel to the vehicle body, returning to its original position after impact. The mirror unit 7, incorporating resilient pads 31 and 32, is attached to an intermediate member 9 forming a frictional ball-joint 8, and this intermediate member is connected to the arm 1 by a tapered set-screw 34. A catch 10, having teeth 26, 26<SP>1</SP> is attached to the arm 1 by a bolt 25 passing through a slotted hole and a toothed lock washer 42, thereby allowing lateral rotational movement of the member 10 relative to the intermediate member 9. The arm is seated on an abutment 6 of the mounting and carries in a slot at its bottom end a flat spring 18, attached to the arm by a bolt 17, whose ends are located in recesses 19. A sliding stop 20 is provided in the top of the mounting with an offset portion 23 which is movable to occupy the open portion of the elongated opening 5 to hold the arm steady when adjustment of the mirror unit is required. When the unit is subjected to an impact it is rotated, together with the arm, against the action of the spring 18. This rotational movement causes one of the teeth, 26<SP>1</SP>, for example, Fig. 7, to engage the stop-face 6 of the mounting, thereby driving the mirror unit and arm inwards towards the vehicle body. In a further embodiment (Fig. 10, not shown) a guide rail extends from the top of the mirror unit, to which it is pivoted, to a bracket on the vehicle body, and a cover may enclose the space between the guide rail, the bracket and the bottom of the mirror mounting.

Title: Fluid-pressure operated materials testing machine
IPC: G01N3/10
Filed: 1957-12-06
Abstract: 846,035. Fluid-pressure servomotor control systems. MASCHINENFABRIK AUSBURGNURNBERG A.G. Dec. 6, 1957 [Dec. 11, 1956], No. 38042/57. Class 135. The ram cylinder 2, of a materials-testing machine, is supplied with pressure air or liquid by a variable-delivery pump 8; the cylinder pressure is transmitted to a gauge 30 having a pointer 32 which indicates pressure, the latter being a measure of the load applied to a testpiece 4; the gauge is also provided with an arm 34 adjustably coupled to the pointer 32 so that it may be disposed at any desired angle with respect thereto. Movement of the arm 34 is transmitted to a pivoted jet 16 by a slipcoupling comprising magnets 35, 36 and a lever 37; the jet 16, which is supplied with air or liquid by a pump 14, has its deflection limited by stops 19, 20 whilst the jet nozzle 16a terminates adjacent channels 26, 27 separated by a deflector 29 and leading to opposite sides of a piston 10 which controls the delivery of the pump 8. To maintain a given pressure in cylinder 2 the pointer 32, arm 34 and lever 37 are relatively adjusted so that pointer 32 indicates the desired pressure, magnets 35, 36 are in alignment and jet 16 is symmetrically located with respect to the ends of channels 26, 27. Any deviation from the set pressure will cause a deflection of members 32, 34 and 16 to cause the piston 10 to appropriately adjust the output of pump 8 to restore the given pressure. When a given pressure is exceeded in the cylinder 2 the movement of the arm 34 is not transmitted by magnets 35, 36 to lever 37. In order to vary the pressure in cylinder 2 at a given rate of change the angle between the pointer 32 and arm 34 is varied at the corresponding rate by a motor, not shown. In a modification, the gauge 30 is rotated by a motor at any given speed; the pointer 32 is connected to a pressure-responsive capsule. If it is desired to control the machine in dependence upon the deformation of the testpiece 4 then arm 34 is mounted upon the testpiece. The machine may also be controlled in dependence upon the force to which the testpiece 4 is subjected in which case the arm 34 is disposed on a ring-member 3 located between the test-piece 4 and ram piston 1. Where testpiece deformation and the force in member 3 are controlling characteristics, means, not shown, is provided for converting linear movement into rotary motion of the pointer. In these circumstances the machine is disposed in a stand with the test-piece bearing on one cross-head and the ring 3 on the other. The gauge casing is preferably made of aluminium which separates the two magnets 35, 36 so that arm 34 does not project from the casing. The gauge is constructed as a plug-in instrument so that it may be used in quick succession to detect any of the above-mentioned signals.

Abstract: 1396505 Servo boosters GIRLING Ltd 11 Aug 1972 [13 Aug 1971] 38063/71 Heading F2F A brake servo-booster of the vacuum suspended type comprises a diaphragm 11 supported by a radially slotted annular deflecting plate 14 which acts to provide "feel", the plate 14 being formed with a plurality of individual, radially extending fingers 40, 42 carried in mutually displaceable relation, the diaphragm having a portion 11a which extends generally radially of the booster axis 17 and an axially extending portion 11b which is located radially outwardly of the deflecting plate 14 and which is supported by an axially extending portion 76a of an annular skirt member 76, the radially outer ends of at least some of the fingers (e.g. fingers 42) being located between radially inwardly projecting parts 76b, 74 of the skirt member 76. As shown in the Figures the deflecting plate 14 has three longer fingers 42 extending close to an output rod 35 operable on a master cylinder piston. An input rod 13 is movable to actuate a control valve 10 comprising a valve seat member 12 and two radially spaced valve seats 24, 26. When rod 13 is moved leftwardly the deflecting plate 14 is distorted about a fulcrum point 72 on a dished plate 18 to close a member 16 against the outer valve seat 26 and move it off the inner seat 24 whereby the right hand side of the diaphragm 11 is connected to atmosphere to move diaphragm 11, deflecting plate 14 and dished plate 18 leftwards with output rod 35. The shorter fingers 42 have recesses 64 to receive studs 66 carried by an annular reaction member 68 which has a flange 10 embedded in a portion of the diaphragm 11 attached to the valve seat member 70, and by virtue of this construction reaction forces produced by the shorter fingers 42 pivoting about their fulcrum point 72 are transferred back to the input rod 13 via the reaction member 68, diaphragm 11 and member 12. The reaction member 68 has slots for the passage of fingers 40 which also pass through a channel-sectioned annular member 62 which acts to distribute reaction forces around the periphery of valve closure member 16. As shown the radially outer ends of shorter fingers 42 are retained in position between a radially inwardly extending limb 76b of skirt member 76 and three arcuate strips 74a, 74b, 74c connected to the portion 76a by arms 78. For a deflecting plate having all fingers the same length the arcuate strips are replaced by a single band extending through 360 degrees and locating all the fingers.
